SimpleXML functions
Brief introduction
The SimpleXML extension provides a very simple and easily usable toolset to convert XML to an object so can be processed With the normal property selectors and array iterators.

Demand
The SimpleXML extension requires PHP 5.

Installation
The SimpleXML extension is enabled by default. To disable it, use the--disable-simplexml configure option.

Or

PHP XML Syntax parsing function
Brief introduction
XML (extensible Markup Language, Extensible Markup Language) is a data format for document exchange on the Web. The language is a standard defined by the World Wide Web Concortium, www organization. You can access http://www.w3.org/XML/to get more information about XML and its related technologies.

This extension provides support for James Clark's expat. The toolkit helps to parse the XML document (not the XML document's validity). It supports the encoding of three source codes, which are supported by PHP itself: Us-ascii, iso-8859-1, and UTF-8. The system does not yet support UTF-16.

This extension enables the user to create an XML parser and define the corresponding processor for different XML events. Each XML parser has several parameters that can be adjusted as needed.

Demand
This extension uses the Expat Compat layer by default. It can also use expat, which can be accessed by http://www.jclark.com/xml/expat.html. The expat Makefile file does not generate a default extension library and can be implemented using the following build rules: Libexpat.a: $ (OBJS)
AR-RC $@ $ (OBJS)
Ranlib $@



Please visit http://sourceforge.net/projects/expat/to get the RPM package for expat source files.

Installation
These functions are valid by default, and they use the bundled expat library. You can block XML support by using the parameter--disable-xml. If you compile PHP as a module of Apache 1.3.9 or later, PHP will automatically use the Apache bundled expat library. If you do not want to use the bundle's expat library, use the parameter--with-expat-dir=dir when you run PHP's configure configuration script, where dir should point to the root of the expat installation.

PHP's version of Windows has built-in support for this extension. You can use these functions without loading any additional extension libraries.
